Bio-Layer Interferometry (BLI) Service

Specific Bio-Layer Interferometry (BLI) Approaches We Offer

The BLI technique refers to the determination of biomolecular interactions. The technique is an optical analysis method for analyzing the interference pattern of white light reflected from two surfaces: the internal reference layer and the precipitated protein layer on the biosensor tip. The change in the interference pattern is caused by any change in the number of molecules bound to the biosensor tip. In this case, interactions can be measured in real time, providing the ability to monitor binding specificity, ratio of binding and dissociation, concentration, fidelity and accuracy. In addition, only molecules bound to or dissociated from the biosensor can alter the interference pattern and generate a response profile on the BLI system. CD BioSciences provides professional bio-layer interferometry (BLI) service to help customers complete biofilm related research.

Specific Bio-Layer Interferometry (BLI) Approaches We Offer

  • Based on an advanced bio-layer interference (BLI) technology platform built over many years and experienced experts in drug discovery, CD BioSciences can provide unparalleled BLI services to meet all your needs.
  • CD BioSciences offers high quality BLI services to identify interactions between identified protein targets and fragments, a critical step in drug discovery. BLI is a useful tool for fragment screening in the drug discovery process. Compared to other methods, BLI offers significant advantages in that it can significantly reduce the false positive rate.
  • CD BioSciences can provide protein interaction services using BLI technology to screen for suitable drug candidates or any other protein interactions you require.
